Note that filter aid selection must be based on planned laboratory tests. Guidelines for selection may only be applied in the broadest sense, since there is almost an infinite number of combinations of filter media, filter aids, and suspensions that will produce varying degrees of separation. The hydrodynamics of any filtration process are highly complex filtration is essentially a multiphase system in which interaction takes place between solids from the suspension, filter aid, and filter medium, and a liquid phase. Experiments are mandatory in most operations not only in proper filter aid selection but in defining the method of application. Some general guidelines can be applied to such studies the filter aid must have the minimum hydraulic resistance and provide the desired rate of separation an insufficient amount of filter aid leads to a reduction in filtrate quality — excess amounts result in losses is filtration rate and it is necessary to account for the method of application and characteristics of filter aids.

The clean-up of contaminated ground water poses problems that are different from contaminated surface waters, particularly because ground water is not easily accessible. Due to the typical slow movement of pollutants in the aquifer and the relatively low degree of dispersion, concentrations of contaminants can remain high and detection can be difficult. In the case of pesticides, some of the factors that may contribute to ground water contamination include physical and chemical properties of the pesticide, application methods used for their application, and characteristics of the soil and site. Once an aquifer is contaminated, its restoration as a usable... 

It is necessary to account for the method of application and characteristics of filter aids. 

Further aspects of protein substantivity to hair are of practical importance. The time course of binding and the relationship between substantivity, protein concentration, number of repeated applications, and characteristics of the vehicle are of great interest to cosmetic chemists to formulate properly with protein derivatives. Substantivity does not necessarily correlate direcfly with conditioning performance for example, excessive accumulation of peptides on the hair surface can impart unwanted hair heaviness, rigidity, and triboelectric charging therefore, detailed evaluation of the conditioning effects of protein derivatives should always be regarded as the key test for their utility in hair care applications.

Since SFRC is more and more widely used in engineering, the need of full understanding of the mechanism of this material with different types of steel fiber is becoming apparent Many people have turned their attention from the pure and basic properties of SFRC to the engineering characteristics, benefits and applications of this material. This paper also gives a general introduction of SFRC with different types of steel fiber and to make a brief description of engineering applications and characteristics of SFRC in China. 

These specifications and characteristics are defined with references to standard test methods which the different parties to a contract should conduct for quality control. The tables that follow show specifically the standards that are applicable in France, but a more general table in Appendix 2 shows the main test methods commonly referenced in specifications. 

The criteria for application and performance characteristics of blowdown drums, cyclone separators, and quench tanks are discussed as follows. 

The presentation will focus on the differences and similarities of these systems as well as problems encountered in their practical use. By looking at the analytical process chain characteristics, such as the reliability and traceability of data, documentation standards and total costs of QM are discussed and evaluated. Suggestions for harmonization of QM-Systems and reduction of bureaucracy will be made, resulting in an improvement of the overall practical applicability and cost reduction of QM. 

The application and use of deep-well turbine and submersible pumps, is extensive and a choice will depend upon the depth of liquid and the rate of discharge. In rocky areas, where the digging of larger well cavity is a difficult task, submersible pumps provide an easy alternative. Similarly, for higher heads and where only a small quantity of liquid is to be pumped, these pumps are preferred. We discuss below the characteristics of these motors and the application of these pumps. 

In the preceding paragraphs we have analysed the behaviour and characteristics of a system when grounded or left isolated. The ground fault factor (GFF) plays a very significant role in the selection of insulation level (BIL) and its coordination with the different equipment connected on the system. The application of a particular method of grounding would thus depend upon... 

Such types of loads may require special design of capacitor elements and their dielectric impregnation, cooling arrangement, size of shell or surface treatment. For all these applications therefore it is important to know the actual operating conditions, behaviour and characteristic of the load and its duty cycle before selecting the capacitors. 

This part deals with the specifications, performance, characteristics and behaviour of motors under different operating conditions, their application and selection. It also covers aspects such as shock loading, motors for hazardous locations and open transient conditions in HT motors during a switching sequence. 

Industrial carbon anodes and artificial graphites are not a single material but are rather members of a broad family of essentially pure carbon. Fortunately, artificial graphites can be tailored to vary widely in their strength, density, conductivity, pore structure, and crystalline development. These attributes contribute to their widespread applicability. Specific characteristics are imparted to the fmished product by conti ollmg the selection of precursor materials and the method of processing [19]... 

The properties of the resins provide information about their suitability for specific applications and may also help to predict some characteristics as aliphatic/ aromatic character, unsaturation degree, etc. 

It is important to note that these applications are typical, but not at all definitive. Fabric filters can be used in almost any process where dust is generated and can be collected and ducted to a centralized location. In general, fabric filters come in many different sizes and configurations. In older plants one can find makeshift operations. See Figures 7 and 8 for examples of common configurations and characteristics.

This discussion will address needs, applications, performance characteristics, and design considerations for LVHV exhaust ventilation. The applications are primarily for dust control. LVHV systems can be effective for protecting workers from dust exposures and for recovering valuable process materials. The equipment, excepting the nozzles, involves technology that is the same as for large central vacuum cleaning systems.
